Application med December 1v, 1am, 'i serial No. temas' To all 'whom it may concern i Be it known that I, AUeUs'r Kms'rnou, a subject of the King of Sweden, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Calculet ing-Machines, of which the following iS a full, clear, and exact description,

In certain types of calculating machines the items are' set up by manipulation of suit? able keysand the mechanism which effects the calculations is actuated by a manual operating lever. For convenience and rapidity of operation it is customary to give the lever a limited; movement, .say through an angle of about or 490-; but it is nevertheless desirable that the main operating shaft, which is actuated by the operating lever .and which transmits motion to the calculating instrumentalities, make n complete rotation, or at least turn through a `greater angle than does the said lever. It is also desirable that this movement of the shafhbe substantially uniform, and that there shall be no possibility of inyury or breakage by too vigorous use of the device in the hands of a careless or inexperienced operator.

My present invention has for its ehi-ef object to provide improved transmission mechanism of the kind referred to, which shall be eiiicient and reliable in operation.

A further object is to provide in conn-ection with such mechanism Ineens for transmitting to the calculating machiney the power of a suitable motor when the machine is to be power-driven instead of bei-ng operated by hand.

To these and other ends the invention consists in the novel features of construction, arrangements of parts, and combinations of elements hereinafter described and more particularly set forth in the claims,

While the invention is capable of various embodiments, I have selected for specific illustration and description hereinonly the preferred construction, which exhibits the invention in convenient and effective form.

Referring now to the annexed drawin s, in which the aforesaid preferred embed'- ment of the inventOIi is illustrated, Figure 1 is a side view of the machine, with a portion of the cesingl broken away to show the interior parte. Fig. 2' is a sectional plan View. Fig. 3 is a section on line 3-3 of Fig. 2. Fig. 4 is a longitudinal sect-ion on line 4 4 of Fig.V 2. Fig. 5 is e detail view of themea'ns for disconnect-ing Athe manual operating lever when the machine is to be driven by a motor. Fig. 6 shows the seme parts as are illustrated in Fig. 5, but. viewed from the opposite side thereof. Fig. 7 is a detail View of the mechanism for trans.- mitting motion from thepower shaft, that is, the shaft to which the power is 1pplied either by the hand or'frorn a suitah e mo tor, to the main operating shaft. in this igfure the parte are shown in their initial positions, before the cycle of movement begine. F 8, 9- and 10 show the sam-e parte as are illustrated in 7, but at diderent stages of the cycle. Fig. 11 is. an end View of Fig. 7 Fig. 12 is an end view of Fig. 8., but with the cam-actuating pawls removed. Fi 13 is a detail sect-ion view on line X II-XIH of Fig. 9, showing the construction of the pivotal connection between the actuating arm (33), and the connecting rod (36) and links (437. 48}, by which me tion is transmitted from the power shaft to the main operating shaft. Fig. 11i is a detail view from the rear of Fig. 10, showing the cam-'actuating pawls and the cam with which they coperate.

The'power shaft of the machine, that is, the shaft to which the power, whether from the hand orfrom a suitable motor, is first communicated is designated by 1. Pinned to this shaft is a hub or sleeve 2 carrying at its inner end a disk 3. 4 Loose on the hub is a. ring or sleeve 4, (Fig. 3), and fast to the latter is a disk 5 adjacent to the first-.mentioned disk 3. Pivoted-to an arm 6 on. disk 5 is a. pawl 7 normally engaging a notch in the disk 3, and held in such engagement by a spring 8 connected to an arm 9 on the opposite side of disk 5. The hub 10 of the manual operating lever 11 fits over the end of the. shaft 1, and is provided with pro.-

ject-io'ns or lugs entering notches lil in the ring 4. Remembering now that the sleeve or huh 2 is pinned to the shaft and that the i to the shaft; in fact the lever and shaft4 will move as though they were integral with each other, the connecting devices Just described being provided tov permit actuation of the shaft at will by a motor instead of by hand, as will be fully explained hereinafter.

On an adjacent-part of the shaft and pinned thereto is a sleeve 13, on which is fixed a disk 14, having an arm 14, and a disk 15 having diametrically arranged arms 16, 17, the last named arm being alongside of arm 14I1 and securely connected thereto by a stud 18, to give the parts the desired strength and rigidity. Pivoted to the arm 16 is a link 19, connected at its rear end to coil springs 20, which are in turn connected to an arm 21 mounted on a rear auxiliary shaft 22 and in rigid connection with an arm 23 extending in the opposite direction. Reaching forwardly from the latter arm, 23, is a long link 24 pivoted to an arm 25 on a hub 26, which is rotatably mounted on the shaft 1 by the roller bearings 27. It will therefore be seen that when. the operating lever 11 is thrown forward, the hub or sleeve 13 and arm 16, turning with the power shaft 1 as before described, will draw link 19 and springs 20 forward, thereby retracting arm 23 and link 24, and that the latter will turn arm 25 and hub 26 on the shaft 1. The hub 26 is itselfsecured fixedly by a set screw 28 to a sleeve 29 loose on t-he shaft and rotatably mounted in roller bearings 30 in the side frame v31. Fast to sleeve 29 is a disk 32 having an upwardly extending arm 33, so that as the operating lever is drawn forward the arm 33 will move in the same direction.

p' On the arm 33 is a crank pin 34, engagi'ng a longitudinal slot 35 in the adjacent forward end of a connecting rod or link 36 which extends rearwardly and has its rear end pivoted to a crank pin 37 on a crank disk 38. The latter is fixed on a transverse shaft 39, the main operating shaft of the machine. When the arm 33 is in 'its normal or initial position, as shown in Fig. 7, the crank pin 37 is on the rearward dead center. For the purpose of throwing the parts off the dead center, and for actuating the crank-disk through certain portions of its movement, the following devices are provided.

` Riveted on the crank-disk is a cam 40, and loose on the shaft alongside of the cam are two arms or dogs 41, 42, carrying pivoted pawls 43, 44, respectively, provided with rollerl studs 45, 46, bearing on the cam. Pivoted to the ends of the dogs are two links 47 48, reaching forward into pivotal connection with the crank-pin 34 on arm 33.

It will now be clear that as the arm 33 turns, in the direction of the arrow in Fig. 7, the crank pin 34 will first move idly in slot 35,but during this movement the links 47, 48 turn thev dogs in opposite directions on shaft 39. The dog 4l carries its pawl 43 idly over the cam, but the other pawl, bearing against the shoulder of the cam, rotates the latter clockwise (as viewed in Fig. 7) and with it the crank-disk 38 and shaft 39. Moreover, it will be seen that since the push of the pawl 44 is exerted substantially at right angles to the line joining the cen# ters of shafts 1 and 39 the power of the former shaft is applied more efficiently than if it were applied through the connecting rod 36. As the cam and crank disk rotate, however, pin 37 is of course carried downward off the dead center, and the forward com-Y ponent of its motion increases, finally equaling the similar component in the motion of stud 46. At this point the former component is still increasing, while the latter is decreasing; hence the connecting rod 36 will now take up the actuation of the disk and the pawl 44 will fall behind. By this time, however, the crank pin 37 has reached the point at right angles to the line between shafts 1 and 39, and hence is applying the power more eiiiciently than would be the case if pawl 44 continued to act, since the latters angle of torque is n'ow considerably less than a right angle.

As the connecting rod 36 continues to act the cam shoulder advances farther and farther from the pawl stud 46, as appears in Fig. 8, and at the same time pawl 43 is appreaching it with an increasing component of forward mo-tion. Fixed on the shaft 39 is a two-bladedcam 39, (Fig. 4), on which bears a roller 39b on the end of a bell crank lever 39C, held against the cam by a strong spring 39d. As the arm 33 and. connecting rod 36 continue their forward movement the cam 39HLA raises lever 39c against the tension of its spring, and the inclined face 39e of the cam approaches the roller 39?. Finally, as the connecting rod approaches the forward dead center the roller 39b drops into cam and by the action of spring 39d gives a strong impulse in the clockwise direction (as viewed in Fig. 4), and, aided by t-he momentum of the machine, carries the cam 40 and crank-disk 38 past the dead center. When the crank-pin 37 is just about at the dead center the shoulder of cani 40 overtakes the pawl 43, and st-ud 45 immediately drops into engagement with the shoulder, as shown in Fig. 9. The operating lever now begins its return movement, and with it the arm 33; but the crank-pin 34 being now at the forward end of the slot 35, the connecting rod 36 does not immediately begin its rearward movement. However, pawl 43, now moving to the rear, is in engagement with the cam shoulder at a torque newness Y gle' 0f Substantially ninety degrees, and

. continuestherotation of the cam, but the crank-pin 37'seon reaches a point where its increasing rearward component of motion uals the decreasing rearward component o 'stud 45 and thereupon takes up the work, in the manner described `in connection with pawl 4 2. As the crank-pin l3'? continues its rearward movement the cam shoulder gains on the pawl, as shown in-Figs.- and 14, but at-.the same time the second inclined edge, 39f, of the cam 39, is approaching the roller 39h; and as the connecting rod approaches the rearward dead center' the cam 39a, in the manner previously described, acts to carry the cam 40 'and crank-disk" 3S l to the initial position, shown in Fig. 7

pawl 42 at that time meeting the shoulder cream 4) and dropping into engagement therewith. A. cycle of movement 1s thus completed, leaving the parts in the positions illustrated in Fig. 7

The return movement of the operating lever 11 can be effected by hand', but l prefer to employ a spring. For this purpose the shaft l is provided with a rigidly mounted arm 49, (Fig. 2), connected by 'a link 50 to the expansible coil spring 51, the rear' end of which is fast to a fixed stud or pin 52.

As previously stated, it is desirable at times to operate the machine by a motor instead of by hand. For this purpose I prefer to have the motor run continuously, and connect it at will to the machine by means of suitable clutch mechanism, such, for eaample, as is described in my copending applica-tion, Ser. No. 437,866, filed' June 11, 1908. The clutch mechanism therein described is idle during the setting up of an -item, but is thrown into action by the op erator by the depression 4of a key (shown in the present drawings at 53, Fig. l) and is automatically thrown out of action at the completion of one rotation of the main operating shaft 39. For the purpose of connecting such clutch mechanism with the power shaft 1, a'link 54 (Figs. 1 and 4) is provided, pivotally connected to a forward extension or arm of the Vdisk l5, so that as the link is drawn down by the motor, operating through -the clutch mechanism, it will rotate the disk 15 and advance the link 19, which, it will be remembered, is the elei ment bywhich the movement -of the operating lever is transmitted to shaft 22. The operating lever 11, as stated above, is connected with the ring 4 iby means of projections on the former entering notches 12 in the latter.

Said lever would move, when the machine is motor-operated, forward and backward if provisions were not made to disengage the lsame from operative vconnection with the main shaftl. Thus when the operator desires 'to use. the motor, he first throws the= lever' farther` to the rear, pastl its: normal position, to its inoperative position., This movement of the lever causes a pin 56cm pawl 7 (see Figs. 5 and 6 to engage a cams stop 57, which promptly1 of engagement with t 1 raws the pawl out e notch in disk 3.-

Remembering now vthatit lis through the f pawl '7 and disk 3 that the lever transmits its power to the shaft 1, it will be seen that the Aaction of the cam-stop disconnects the lever from the shaft and allows the hub le), to which the lever is connected, and the rin Ltlsogvether with its disk 5 to have la free an loose connection upon lthe power shaft l whereby the vsame Vwill remain `stat-io-i'iary during rthe time that the same is connected to the motor. On desiring to use thelever again, thevoperator simply draws it forward, whereupon the pawl 7, dsend from the cam-stop, snapsback into its notch disk 3.

The means of connecting the arm 54 with the clutch shaft is shown 1n Fig. 4 comprising a slot 54 in the 4said arm and a pin c olf the crank arm C cooperating with said s ot.
